Samper Silk Screen promotion

Samper Silk Screen printers in Los Angeles asked Bob Zoell to create six images to show off the excellence of their printing. Eleven inches square with a gloss cover, the yellow six on the front has a black keyline and a gold drop shadow.
    The art inside is printed with fourteen separate colors, the center has eleven of them, the Camel pack uses a silver for the background. Zoell was born in Canada in 1940 but moved to LA in 1962 where he became well known as an illustrator (seven New Yorker covers) and in 1970 to develop his own style of abstract art.
    I think the company send out the promotion in the eighties but I don't think they are in business now.
